    @nixem – On the power supply question, I saw an interesting video with Laurie Fincham just now (https://www.youtube.com/watch?v=n1eIIb7DvLQ). In it, when they discussed the 120dB speaker that they built, it said in the article they used 3 power supplies to power 8 amplifiers for a 1600W speaker. If you look at your question, I would, on this basis, look into using 2 power supplies for the 4 boards. This would ensure proper loading without having as much to worry about. Just wanted to throw that bone I found to you.
